Anatoma is a genus of minute marine gastropod molluscs or micromolluscs in the family Anatomidae, found in Europe, Australia and New Zealand.

They were formerly placed as a subfamily in the family Scissurellidae. They were raised to family level by Geiger and Jansen in 2004.

Description

Anatoma snails have conical or top-shaped (turbiniform) shells. The shell often features a slit or hole in the margin of the outer lip and possesses a deep, perspective umbilicus. This genus is further characterized a rhipidoglossate radula, and a lack of nacre. Their shells may be sculptured with longitudinal lamellae and transverse lines, along with ornamentation like concentric elevated lirae.
